Description

Technical Field

[0001] The present disclosure generally relates to an air flow environment system, and more particularly to an air flow environment system that forms an air flow in an environmental space.

Background Art

[0002] As a conventional example, referring to FIG. 6, an air purifying device 100 described in Patent Document 1 will be exemplified. FIG. 6 is an external perspective view showing the structure of a conventional air purifying device 100. As shown in FIG. 6, the conventional air purifying device 100 is installed for a smoking area 101 that is an open space, and includes furniture 102 disposed in front of the smoking area 101 and an intake unit 103 installed on the smoking area 101 side. In the air purifying device 100, an air flow 105 discharged from an exhaust port 104 of the furniture 102 incorporating an air discharge unit is circulated obliquely upward toward an intake opening 106 in the intake unit 103 and sucked into the intake opening 106. According to such an air purifying device 100, since tobacco smoke and the like are involved by the air flow 105 directed obliquely upward, the outside space that is a non-smoking area and the inside space that is a smoking area are blocked, and the diffusion of tobacco smoke and the like to the outside area can be suppressed.

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, according to the conventional air purifier, although the air flow between the outer space and the inner space (environmental space) can be suppressed by the upwardly inclined air flow, there is not enough room for air to flow in and out on the side of the smoking area to confine the air flow within the inner space and improve the comfort (air feeling, cool feeling, cleanliness, etc.) for the user. That is, it is desirable to improve the comfort of the user in the environmental space.

[0005] In view of the above reasons, the present invention is made, and an object thereof is to provide an air flow environment system capable of improving the comfort of the user in the environmental space.

Means for Solving the Problems

[0006] And, in order to achieve this object, the air flow environment system according to the present invention generates an air flow in a specific space having an open surface whose front side is open to the external space. The air flow environment system includes an air outlet that discharges an air flow flowing along a specific direction to the specific space on the back side of the specific space, and a reflection part that is arranged so as to face the air outlet in a specific direction and against which the air flow flowing along the specific direction hits. And, the reflection part is configured to reflux the hit air flow to the floor surface side of the specific space so as to cross the open surface on the front side of the specific space, and thereby achieves the above-described object.

[Figure 6] Figure 6 is an external perspective view showing the structure of a conventional air purifier. [Modes for carrying out the invention]

[0009] The airflow environment system according to the present invention generates an airflow in a specific space, where the front side is an open surface that is open to the outside space. The airflow environment system comprises an outlet that releases airflow flowing in a specific direction into the specific space on the back side of the specific space, and a reflecting part that is positioned opposite the outlet in a specific direction and is struck by the airflow flowing in a specific direction. The reflecting part is configured to return the struck airflow to the floor side of the specific space, traversing the open surface on the front side of the specific space.

[0010] With this configuration, the airflow reflected by the reflector returns to the floor side of the specific space, crossing the open surface on the front side of the specific space, thus confining the airflow within the specific space. Furthermore, an induced airflow (induced airflow) is created by the airflow flowing along a specific direction on the back side of the specific space, generating an airflow from the front to the back side of the specific space, allowing users of the specific space to feel the airflow. In other words, it is possible to improve user comfort within the specific space compared to using conventional air purification devices. In short, it is possible to create an airflow environment system that can improve user comfort within a specific space.

[0011] Furthermore, in the airflow environment system according to the present invention, a seat where a user can sit is installed in a specific space. The specific space has an open surface on the front side of the seat that is open to the outside space, and the discharge port may be configured to discharge airflow flowing in a specific direction on the back side of the seat into the specific space. In this way, the airflow reflected by the reflector returns to the floor side of the seat, crossing the open surface on the front side of the seat, so that the airflow can be contained within the specific space. Then, an airflow (induced airflow) is created in the specific space from the front side to the back side by the airflow flowing along the specific direction on the back side of the seat, so that the user using the seat can feel the airflow. In other words, the comfort of the user using the seat in the specific space can be improved compared to using a conventional air purification device.

[0012] Furthermore, in the airflow environment system according to the present invention, it is preferable that the outlet is located lower to the floor level than the user's head position so that an airflow flows in a specific direction between the user seated in the seat and the wall surface constituting a specific space exposed behind the user. By doing so, an induced airflow is generated behind the user, including their head, so that the user can more reliably feel the airflow from the front to the back within the specific space. In other words, the user's comfort within the specific space can be effectively improved.

[0013] Furthermore, the airflow environment system according to the present invention is further provided with an air intake port on the floor side of the seat area that draws in air from a specific space, and the discharge port directs the air drawn in from the air intake port in a specific direction. It may also be configured to release the airflow along the reflective section. With this configuration, the airflow reflected by the reflective section is drawn in by the intake, so the airflow can be more reliably contained within the specific space. This allows for a more stable flow of air (induced airflow) to be generated within the specific space.

[0014] Furthermore, the airflow environment system according to the present invention further includes a functional unit that adds an additional element to the airflow discharged from the outlet into a specific space, and it is preferable that the additional element includes at least one of fragrance, air purification, humidity change, and temperature change. In this way, the additional element can be added to the airflow and the specific space can be filled with the additional element. Since the diffusion of the additional element to the outside of the specific space is suppressed by the airflow reflected by the reflecting unit, it becomes easier to maintain the state in which the specific space is filled with the additional element. In other words, the comfort of the user within the specific space can be further improved.

[0015] Furthermore, the airflow environment system according to the present invention further comprises a central air conditioning room that introduces air from outside a specific space and adds an additional element, and a duct that connects the central air conditioning room and an outlet. The additional element includes at least one of fragrance, air purification, humidity change, and temperature change, and the outlet may be configured to release the air introduced from the central air conditioning room as an airflow that flows along a specific direction. With this configuration, since air (air with the additional element added) is supplied from the central air conditioning room to the airflow environment system, it can be easily applied to airflow environment systems having multiple independent specific spaces.

[0016] Embodiments of the present invention will be described below with reference to the drawings. Note that the following embodiments are merely examples of the present invention and do not limit the technical scope of the present invention. Furthermore, the figures described in the embodiments are schematic diagrams, and the ratios of the size and thickness of each component in each figure do not necessarily reflect the actual dimensional ratios.

[0017] (Embodiment 1) First, an overview of the airflow environment system 1 according to Embodiment 1 will be described with reference to Figures 1 and 2. Figure 1 is an external perspective view of the airflow environment system 1 according to Embodiment 1 of the present invention. Figure 2 is a block diagram showing the configuration of the blowing system 2 in the airflow environment system 1.

[0018] In the following description, the airflow environment system 1 is described with the left - right direction (left side, right side), up - down direction (lower floor surface, upper ceiling surface), and front - back direction (front on the near side, back on the far side) defined in the state of viewing the airflow environment system 1 from the front.

[0019] The airflow environment system 1 is, for example, installed as a private room unit 10 that also serves as a rest room, waiting room, etc., and is configured to form a comfortable airflow (air current) for the user U (see FIG. 3) in a specific space SP1 formed within the private room unit 10. Note that the specific space SP1 can also be referred to as an environmental space.

[0020] As shown in FIG. 1, the airflow environment system 1 includes a box - type private room unit 10, a seat portion 3 equipped with a blowing system 2, and a reflecting portion 4.

[0021] The private room unit 10 is surrounded by a left wall surface 10a, a right wall surface 10b, a floor - side wall surface 10c, a ceiling - side wall surface 10d, and a back - side wall surface 10e, and has an open surface X on the front side of the seat portion 3 that is open to the external space SP2. Note that the "open surface X" is a virtual surface without an entity, and is a virtual surface surrounded by the front - side ends of the left wall surface 10a, the right wall surface 10b, the floor - side wall surface 10c, and the ceiling - side wall surface 10d. And inside the private room unit 10, a seat portion 3 equipped with a blowing system 2 is installed on the floor side and a reflecting portion 4 is installed on the ceiling side.

[0022] The blowing system 2 (the seat portion 3 equipped with the blowing system 2) is installed on the floor - side wall surface 10c within the specific space SP1 and discharges an air current A1 (see FIG. 3) flowing along a first direction (the direction indicated by the arrow showing the air current A1 in FIG. 3) in a specific direction into the specific space SP1. The reflecting portion 4 is installed at a position facing the blowing system 2 in the first direction on the ceiling - side wall surface 10d within the specific space SP1, and the air current A1 flowing along the first direction hits it. Then, the reflecting portion 4 is configured to reflux the hit air current A2 to the floor side (the direction indicated by the arrow showing the air current A3 in FIG. 3) within the specific space SP1.

[0023] Specifically, the seat section 3 equipped with the ventilation system 2 will be described.

[0024] The seat section 3 has a base and a backrest on which a user can sit. Furthermore, the seat section 3 can also be said to constitute a component of the outer frame of the ventilation system 2, and is comprised of the ventilation system 2, an outlet 5, and an intake 6.

[0025] The discharge port 5 is located, for example, on the upper surface of the backrest of the seat 3. The discharge port 5 is composed of a slit-shaped opening (or multiple holes) extending from the left wall surface 10a to the right wall surface 10b. The discharge port 5 is configured to communicate with the blowing system 2 and discharges the air blown from the blowing system 2 into the specific space SP1 as an airflow A1 flowing along the first direction. In particular, the discharge port 5 is positioned lower than the position of the user U's head (towards the floor) so that the airflow A1 flowing along the first direction flows between the user U and the wall surface 10e exposed behind the user U (see Figure 3). Here, the position of the user U's head refers to the position of the head of a user U with at least a standard sitting height when seated in the seat 3 in the correct posture.

[0026] The air intake 6 is located on the floor-facing front of the base of the seat section 3 and consists of, for example, multiple slit-shaped holes that are elongated in the vertical direction. The air intake 6 is configured to communicate with the air blowing system 2 via the internal space (not shown) of the seat section 3, and as the air blowing system 2 operates, it draws air from a specific space SP1 into the internal space.

[0027] As described above, the ventilation system 2 is configured to be housed or held inside the seat section 3. The ventilation system 2 is also connected to the outlet 5 and the intake 6 within the internal space of the seat section 3. Air from the specific space SP1 is supplied to the ventilation system 2 from the intake 6 and discharged back into the specific space SP1 from the outlet 5.

[0028] Specifically, the blower system 2 is configured to include a blower 2a and a functional unit 2b, as shown in Figure 2.

[0029] The blower 2a is a device that, under the control of a control unit (not shown), draws air from a specific space SP1 through an intake port 6, generates an airflow A1 that flows along a first direction (vertically upward direction), and sends it out to an outlet port 5. The blower 2a is, for example, a sirocco fan that generates an airflow that contains more of a straight-line component than a swirling component. The blower 2a draws air from a specific space SP1 through an intake port 6 and generates an airflow A1 that flows along a first direction. Here, the material of the blower 2a is not particularly limited, but it is desirable that the material's durability is not affected by the additional elements that are applied to the airflow discharged from the outlet port 5 to the specific space SP1 by the functional unit 2b, which will be described later.

[0030] Functional unit 2b is a device that adds an additional element to the airflow released from outlet 5 into a specific space SP1. The additional element is one of the following: fragrance, air purification, humidity change, and temperature change. Each includes one.

[0031] If the additional element includes fragrance, the functional unit 2b is housed within the seat unit 3. The additional element includes, for example, a fragrance-distributing device containing an air freshener. The fragrance vaporized from the air freshener mixes with the airflow from the blower 2a to the outlet 5. As a result, a pleasantly scented air can be provided to the user U in the specific space SP1.

[0032] If the additional element includes air purification, the functional unit 2b may, for example, have an air purifier. The air purifier is housed within the seat unit 3. The air purifier includes a dust collection filter for collecting fine particles such as pollen in the air drawn in from the air intake 6, and a deodorizing filter, etc. The air purified by the air purifier is discharged upward as an airflow from the outlet 5 by the blower 2a. As a result, purified air can be provided to the user U in the specific space SP1.

[0033] If the additional element includes air purification, the functional unit 2b may, for example, have a space sterilization and deodorization device. The space sterilization and deodorization device is housed within the seat unit 3. The space sterilization and deodorization device is configured to generate hypochlorous acid and mix it with the airflow generated by the blower 2a. The airflow containing hypochlorous acid is released upward from the outlet 5 to sterilize the specific space SP1. As a result, purified air can be provided to the user U in the specific space SP1.

[0034] If the additional element includes humidity changes, the functional unit 2b may, for example, have a dehumidifying and humidifying device. The dehumidifying and humidifying device is housed within the seat unit 3. The air conditioned (dehumidified or humidified) by the dehumidifying and humidifying device is released upward as an airflow from the outlet 5 by the blower 2a. As a result, the user U in the specific space SP1 can be provided with air at a comfortable humidity level.

[0035] If the additional element involves temperature changes, the functional unit 2b may include, for example, an air conditioning unit. The air conditioning unit has a compressor, and the cool or warm air generated by the air conditioning unit is discharged upward as an airflow from the outlet 5 by the blower 2a. As a result, a comfortable temperature of air can be provided to the user U in the specific space SP1.

[0036] If the functional unit 2b includes the air purifier, space sterilization and deodorization device, dehumidification and humidification device, and air conditioning device described above, their power can be turned on or off, and various parameters can be adjusted, for example, by operating an operation panel (not shown). The operation of the functional unit 2b may be controlled under the control of the control unit in conjunction with the operation of the blower 2a.

[0037] By providing the functional unit 2b to the blowing system 2 in this way, additional elements can be easily added to the airflow.

[0038] Next, the reflective section 4 will be described with reference to Figure 3. Figure 3 is a schematic diagram illustrating the airflow formed by the airflow environment system 1.

[0039] As shown in Figure 3, the reflective section 4 is installed on the wall surface 10d on the ceiling side of the private room unit 10. The reflective section 4 is positioned to face the discharge port 5 in the first direction (vertically upward direction), and the lower surface of the reflective section 4 (the surface facing the discharge port 5) has a curved surface 4a that is approximately semi-cylindrical (semi-circular) with a recess in the center. Specifically, the approximately semi-cylindrical curved surface 4a has an axial direction that is approximately parallel to the open surface X and the wall surface 10c on the floor side, and when viewed along the axial direction, it is curved in an arc shape so as to be convex toward the ceiling side.

[0040] In the reflecting section 4, when the airflow environment system 1 (blowing system 2) is operating, the airflow A1 (airflow A1 flowing along the first direction) released from the outlet 5 strikes the curved surface 4a of the reflecting section 4. Then, the airflow that strikes the curved surface 4a is reflected along the curved surface 4a in the second direction. The airflow is reflected and flows in the direction from the back to the front. Furthermore, the airflow A2 flowing in the second direction is discharged from the front end of the curved surface 4a toward the floor (in the direction indicated by the arrow showing airflow A3 in Figure 3). In other words, the reflecting section 4 is configured such that the airflow A1 flowing along the first direction strikes it, and the struck airflow A2 (airflow A2 flowing in the second direction) is returned to the floor of the seat section 3 so as to traverse the open surface X on the front side of the seat section 3 in the vertical direction.

[0041] Next, with reference to Figure 3, the airflow of the airflow environment system 1 will be described.

[0042] In the airflow environment system 1, as described above, the blowing system 2 discharges an airflow A1 from the outlet 5 along the first direction. Here, the airflow A1 discharged from the outlet 5 flows along the wall surface 10e due to the Coanda effect (a negative pressure region is generated between the discharged air and the wall surface 10e, and the discharged airflow is drawn towards the negative pressure region). The airflow A1 discharged from the outlet 5 then strikes the curved surface 4a at the rear end of the curved surface 4a in the reflecting section 4. The airflow A2 that strikes the curved surface 4a then flows along the curved surface 4a so as to be reflected in the second direction. The airflow A2 that has flowed in the second direction is then discharged from the front end of the curved surface 4a toward the floor as an airflow A3 flowing in the third direction (from the ceiling side toward the floor side). The released airflow A3 then traverses the open surface X of the private room unit 10 in the vertical direction (from the ceiling side to the floor side) and flows towards the floor. The airflow A4 that has flowed towards the floor then flows along the wall surface 10c in a fourth direction (from the front side to the back side) and is drawn in through the air intake 6 of the seat section 3. The drawn-in airflow is then released again by the ventilation system 2 as airflow A1 flowing along the first direction. In this way, a series of airflows (airflows A1 to A4) are formed within the specific space SP1.

[0043] In the airflow environment system 1, the airflow A3 that traverses the open surface X in the vertical direction functions as an air curtain, thereby suppressing the airflow between the specific space SP1 and the external space SP2. At this time, the left wall surface 10a and the right wall surface 10b suppress the inflow of air into the private room unit 10 or the outflow of air to the outside of the private room unit 10, thus confining the airflow within the specific space SP1.

[0044] Furthermore, in the airflow environment system 1, an induced airflow B1 is generated on the back side of the seat 3 by the airflow A1 flowing along the first direction. In addition, this induced airflow B1 creates an airflow (induced airflow B2) that moves from the front to the back within the specific space SP1. As a result, the series of airflows (airflows A1 to A4) create an induced airflow (induced airflow B1, induced airflow B2) that moves from the front to the back within the specific space SP1. In other words, the user U using the seat 3 can feel this airflow.

[0045] As described above, the airflow environment system 1 can confine air within a specific space SP1 and generate airflow within the specific space SP1, where the front side of the individual room unit 10 is an open surface X that is open to the external space SP1.

[0046] As described above, the following effects can be enjoyed with the airflow environment system 1 according to this embodiment 1.

[0047] (1) The airflow environment system 1 includes an outlet 5 that releases an airflow A1 flowing in a first direction into a specific space SP1 on the back side of the seat section 3, and a reflector 4 that is positioned opposite the outlet 5 in the first direction and is struck by the airflow A1 flowing in the first direction. The reflector 4 is used to direct the airflow A2 that strikes it across the open surface X on the front side of the seat section 3. The system is configured to recirculate the airflow towards the floor side of the seat section 3. In this way, the airflow A3 reflected by the reflector 4 recirculates towards the floor side of the seat section 3, crossing the open surface X on the front side of the seat section 3, thus confining the airflow within the specific space SP1. Furthermore, the airflow (induced airflow B1) induced by the airflow A1 flowing along the first direction on the back side of the seat section 3 generates an airflow (induced airflow B2) from the front to the back side within the specific space SP1, allowing the user U using the seat section 3 to feel the airflow. In other words, it is possible to improve the comfort of the user U within the specific space SP1 compared to using a conventional air purifier. In short, it is possible to create an airflow environment system 1 that can improve the comfort of the user U within the specific space SP1.

[0048] (2) In the airflow environment system 1, the outlet 5 is positioned lower on the floor side than the position of the user U's head, so that an airflow A1 flowing in the first direction flows between the user U seated in the seat 3 and the wall surface (wall surface 10e) that constitutes a specific space exposed behind the user U. As a result, an induced airflow B1 is generated behind the user U, including the user U's head, so that the user U can more reliably feel the airflow (induced airflow B2) moving from the front to the back within the specific space SP1. In other words, the comfort of the user U within the specific space SP1 can be effectively improved.

[0049] (3) In the airflow environment system 1, an intake port 6 is provided on the floor side of the seat section 3 to draw in air from the specific space SP1, and the discharge port 5 is configured to release the air drawn in from the intake port 6 (air including airflow A4) as airflow A1 flowing along the first direction. As a result, the airflow A3 (and subsequent airflow A4) reflected by the reflector section 4 is drawn in by the intake port 6, so that the airflow can be more reliably contained within the specific space SP1. This makes it possible to generate a more stable flow of air (induced airflow B1 and induced airflow B2) formed in the specific space SP1.

[0050] (4) In the airflow environment system 1, a functional unit 2b is provided that adds an additional element to the airflow A1 released from the outlet 5 into a specific space SP1, and the additional element includes at least one of the following: fragrance, air purification, humidity change, and temperature change. This allows the additional element to be added to the airflow A1, filling the specific space SP1 with the additional element. Furthermore, the diffusion of the additional element to the outside of the specific space SP1 (outer space SP2) is suppressed by the airflow A3 reflected by the reflecting unit 4, making it easier to maintain the state in which the specific space SP1 is filled with the additional element. In other words, the comfort of the user U within the specific space SP1 can be further improved.

[0051] (Embodiment 2) The airflow environment system 1a according to Embodiment 2 of the present invention differs from Embodiment 1 in that it is configured to receive airflow from a centralized air supply system 12 instead of airflow from a blower system 2. The other configurations of the airflow environment system 1a are the same as those of the airflow environment system 1 according to Embodiment 1. Hereinafter, explanations of aspects already described in Embodiment 1 will be omitted as appropriate, and the differences from Embodiment 1 will be described primarily.

[0052] The airflow environment system 1a according to Embodiment 2 of the present invention will be described with reference to Figure 4. Figure 4 is a schematic diagram of the airflow environment system 1a according to Embodiment 2 of the present invention.

[0053] As shown in Figure 4, the airflow environment system 1a is configured to communicate with the centralized ventilation system 12 via a duct 11. The centralized ventilation system 12 corresponds to the "centralized air conditioning room" in the claim.

[0054] The duct 11 is connected to the discharge port 5 from the internal space of the seat section 3. For this reason, the seat section 3 does not have an air intake port 6.

[0055] The centralized ventilation system 12 consists of a blower 12a and a functional unit 12b, each having the same functions as the ventilation system 2 (blower 2a and functional unit 2b). The centralized ventilation system 12 is installed in an air conditioning room or similar location, away from the airflow environment system 1a, and is configured to supply air to the airflow environment system 1a. Therefore, the centralized ventilation system 12 takes in air from outside the specific space SP1 (air from the external space SP2) and supplies it to the airflow environment system 1a. On the other hand, the centralized ventilation system 12 is also connected to an airflow environment system 1b, which is different from the airflow environment system 1a. This makes it possible to supply air to multiple airflow environment systems.

[0056] Furthermore, in the airflow environment system 1a, similar to the airflow environment system 1, in a specific space SP1 where the front side of the individual room unit 10 is an open surface X that is open to the external space SP1, it is possible to confine air within the specific space SP1 and generate airflow within the specific space SP1. In the airflow environment system 1a, the airflow A3 flowing in the third direction is designed to diffuse along the floor surface.

[0057] As described above, the following effects can be enjoyed with the airflow environment system 1a according to this second embodiment.

[0058] (5) The airflow environment system 1a includes a centralized air supply system 12 that introduces air from outside the specific space SP1 (external space SP2) and adds an additional element, and a duct 11 that connects the centralized air supply system 12 and the outlet 5. The additional element includes at least one of the following: fragrance, air purification, humidity change, and temperature change. The outlet 5 is configured to release the air introduced from the centralized air supply system 12 as an airflow A1 that flows along the first direction. As a result, since air (air with the additional element added) is supplied from the centralized air supply system 12 to the airflow environment system 1a, it can be easily applied to an airflow environment system 1b that has multiple independent specific spaces SP1.

[0059] (Embodiment 3) The airflow environment system 1c according to Embodiment 3 of the present invention differs from Embodiment 1 in that it is composed of a blower unit 3a equipped with a blower system 2 instead of a seat section 3 equipped with a blower system 2. The other configurations of the airflow environment system 1c are the same as those of the airflow environment system 1 according to Embodiment 1. Hereinafter, explanations of contents already described in Embodiment 1 will be omitted as appropriate, and the differences from Embodiment 1 will be mainly described.

[0060] The airflow environment system 1c according to Embodiment 3 of the present invention will be described with reference to Figure 5. Figure 5 is a schematic diagram of the airflow environment system 1c according to Embodiment 3 of the present invention.

[0061] In the airflow environment system 1c, as shown in Figure 5, there is no seating area inside the box-shaped private room unit 10 with an open surface X where a user U can sit. Therefore, the user U will use the private room unit 10 while standing.

[0062] As shown in Figure 5, the blower unit 3a is installed on the wall surface 10c on the floor side of the specific space SP1, adjacent to the wall surface 10e on the back side. The blower unit 3a then releases an airflow A1 into the specific space SP1 that flows in a specific direction, the first direction (the direction indicated by the arrow indicating airflow A1). The reflector 4 is installed on the wall surface 10d on the ceiling side of the specific space SP1, opposite the blower unit 3a in the first direction, and is struck by the airflow A1 flowing in the first direction. The reflector 4 then strikes the airflow A1 in the specific space SP1. The system is configured to recirculate the airflow A2 toward the floor (in the direction indicated by the arrow showing airflow A3).

[0063] Specifically, we will describe the blower unit 3a equipped with the blower system 2.

[0064] The blower unit 3a can also be said to be a component that makes up the outer frame of the blower system 2, and is composed of the blower system 2, an outlet 5a, and an intake port 6a.

[0065] The discharge port 5a is located on the upper surface of the blower unit 3a. Although not specifically shown in the figures, the discharge port 5a, like the discharge port 5, is composed of a slit-shaped opening (or multiple holes) extending from the left wall surface 10a to the right wall surface 10b. The discharge port 5a is configured to communicate with the blower system 2 and discharges the air blown from the blower system 2 into the specific space SP1 as an airflow A1 flowing along the first direction. The position where the discharge port 5a is formed (height from the floor) is approximately the same height as the position where the discharge port 5 is formed in the seat section 3.

[0066] The air intake port 6a is located on the floor-facing front of the blower unit 3a and consists of, for example, multiple slit-shaped holes that are elongated in the vertical direction. The air intake port 6a is configured to communicate with the blower system 2 via the internal space (not shown) of the blower unit 3a, and as the blower system 2 operates, it draws air from a specific space SP1 into the internal space.

[0067] As described above, the blower system 2 is configured to be housed or held inside the blower unit 3a. The blower system 2 is also connected to the outlet 5a and the intake 6a, respectively, within the internal space of the blower unit 3a. Air from the specific space SP1 is supplied to the blower system 2 from the intake 6a and discharged back into the specific space SP1 from the outlet 5a.

[0068] The airflow formed by the airflow environment system 1c is the same as the airflow formed by the airflow environment system 1, so its explanation will be omitted.

[0069] As described above, the airflow environment system 1c can confine air within a specific space SP1 and generate airflow within the specific space SP1, where the front side of the individual room unit 10 is an open surface X that is open to the external space SP1.

[0070] As described above, the following effects can be enjoyed with the airflow environment system 1c according to this embodiment 3.

[0071] (6) The airflow environment system 1c includes an outlet 5a that releases an airflow A1 flowing along a first direction into the specific space SP1 on the back side of the specific space SP1, and a reflector 4 positioned opposite the outlet 5a in the first direction, to which the airflow A1 flowing along the first direction strikes. The reflector 4 is configured to return the struck airflow A2 to the floor side of the specific space SP1 so as to cross the open surface X on the front side of the specific space SP1. In this way, the airflow A3 reflected by the reflector 4 returns to the floor side so as to cross the open surface X on the front side of the specific space SP1, thereby confining the airflow within the specific space SP1. Furthermore, the airflow (induced airflow B1) induced by the airflow A1 flowing along the first direction on the back side of the specific space SP1 generates an airflow (induced airflow B2) from the front side to the back side of the specific space SP1, so that users U using the specific space SP1 while standing can feel the airflow. In other words, compared to using conventional air purifiers, it is possible to improve the comfort of user U within a specific space SP1.

[0072] Although the present invention has been described above based on embodiments, it can be easily inferred that the present invention is not limited in any way to the above embodiments, and that various improvements and modifications are possible without departing from the spirit of the present invention.

[0073] In the airflow environment system 1 according to this embodiment 1, an air intake 6 is provided in the seat section 3 to circulate the airflow, but the system is not limited to this. For example, the air intake 6 may not be provided, and the airflow A3 flowing in the third direction may be configured to diffuse along the floor surface. The above-described effects can also be enjoyed with such a configuration.

[0074] Furthermore, in the airflow environment system 1 according to this embodiment 1, the discharge port 5 is provided on the upper surface of the backrest of the seat 3, but this is not the only option. For example, a gap may be provided between the seat 3 and the wall surface 10e, and the discharge port 5 may be placed in that gap. This increases the design flexibility of the airflow environment system 1. [Industrial applicability]

[0075] As described above, the airflow environment system according to this embodiment is useful because it can improve user comfort within the environmental space. [Explanation of symbols]
